qw- To all whom 'it may concern: I

' Beit known that I, J 0111s .1). WISE, of German township, Holmes county, and State of Ohio, have invented a Method ofUtilizling the Slag of Iron-Furnaces in the Productionof' Block fo'r Building and other Purposes; and Ido hereby declare that the followingisa full, clear, aud exact description thereof', reference being had to the accompanying drawings, 'making a part of this specification, in which- '4 7 Figure l is a perspective view of a moulded' block of' slag, with one corner broken away, to show the. strengthening-band which is moulded in the block.

Figure 2 is a cross-section through the centre of a tlaslr, howing a block of the slag in it, ready to be remover .l

d Bigure 3! is a longitudinal central section through the as I Figure 4 is a top'view ofthe flask.

Figure 5 is a perspective view of a strengtheningband, with its supports, and corner-strengthening wires.

Similar letters of reference indicate Acorresponding parts in the several figures. l

The object of' this invention is'to utilize the slag or waste of iron-furnaces, by 'moulding the slag ntorect- A augularor other-shaped blocks, suitable for building, paving,r and other analogous purposes:

I I have discovered that the slag which is drawn from furnaces, inthe process of` smlting iron-ore, and which has 'heretofore been thrown away as useless, will, if moulded in proper iiasks, produce very h ard and dura ble blocks, which are well adapted for use in the construction of' buildings, and for paviugp'urposes.

The following is 'a description of one practical Inode of'nioulding the slag into a useful form:

I employ a metal dusk, in order that it shall not' be seriously injured' by the heat to which it is subjected, and construct this liask of four or'more plates or sections united together, so that, after a block is moulded within the flask, they can be readily separated, to allow of' the removal of' the block. 1

C is the top plate or section, which, in the present instance, is rectangular, with a pouring-hole, p, through its' centre, as shown iu tigs.,2,l 3, and 4.

E is the bottom section, which is of the Same size and shape as the top section, and which has lugs, or forked offsets, on two of its edges, for receiving and holding the lower endsoi two clamping-rods, l F, by which the several Sections of the ask are confined in place.

which *may be, for convenience, secured permanently' together in pairs.

Ilhc abutting-surfaces of the several plates or sections may be provided with dowel-pins, fitting in correspoudiug-holes, so'as td' make strong and tight joints at the angles ofthe ilask.

at a, in figs. 1 and 2.

J J are the perpendicular side plates of the flask,

To put the sections of the flask together, the" 'sido plates J J are adjusted on top of thebottomplateE, .and on top of' these side plates the cover O is put-'1,'

This cover C- has slotted, or forked'lugs d e, upon its edges, which, when the plates C andE are' in their proper places, are directly over the lugs t 'if on plate E.

The rod F, with heads g on both ends, confines one side of. the iiask-plates, and the opposite bar F, which has a head, g, en its lower end, and a key, j, passed through it, over plate C, contines the other side of the ilask. Other means may be adopted for confining the desk-sections together.

Before putting the top plate O on the ask, `a narrow baud, B, iig. 5, of a rectangular form,tand somewhat smaller than the interior chamber of the ask, is adjusted centrally within this chamber, by supporting -it upon' the bottom fof the flask, by means of the ver- 1 tical wires 1f b, applied at its four angles.

. Figs. l, 2,4 and 3, show'this band embeddedin the body of theI casting A, with its upright wires b l), in the four corners of the casting.

If desirable, one or more of the inner surfaces ofthe flask-plates may have elevations and depressions formed von them, ibrproducing, in converse order, corresponding figures upon the exterior surface o'r surfaces of the block A, thereby omamenting the same, as indicated When the flask-sections have been confined together in a p'roper manner, tlie flask is takenA to the ironfurnace, and, at a suitable timegfor drawing off the'slag, Athe furnace is opened at the proper point, and the melted slag run directly into the mould, producing, when cool, a block, A, which is prevented from cracking, while cooling, bythe metallic baud lB, embedded in' it, as above shown.

Blocks, thus produced, possess great strengthy and solidity, and are Vwell adapted for the purposes above named; They have a dark color, and Ypresent glazed surfaces, resembling a finely-finished polish. For build# ing-purposes, theyv may be moulded of any required size and shape; and, if found necessary, the blocks or slabs may be produced with chambers in or through them for receiving mortar, by which to unite the. blocks to-f gether, in a building.

Having described my invention, That I claim as new, and desire to secure by L etters Patent, is- 4 A brick or block made from slag, and Stayed and held together by 'internal devices, substantially as described. y
